Introduction

Some 2004 – 2009 model year Highlander, 2001 – 2005 model year RAV4, and 2004 – 2010 modelyear Sienna AWD (4WD) vehicles may display a transmission fluid or gear oil seepage from a venton the right side of the transfer case. The seepage is from the transfer RH (right-hand) bearingretainer No. 2 oil seal. Production improvements have been implemented to prevent this conditionfrom occurring. Follow the repair procedure in this bulletin to replace the RH bearing retainer No. 2oil seal assembly.

Repair Procedure: Installation

1. Install a NEW No. 2 oil seal in the RH bearing retainer.

NOTEThe No. 2 oil seal MUST be positioned so that the seal is aligned over the hole located insidethe RH bearing retainer. Failure to properly align the seal so that it seals on BOTH sides ofthe hole (vent) will cause the transfer case to leak fluid out of the vent assembly on the RHbearing retainer.

Figure 12.

NOTEOnly the outer race of the center differential case tapered roller bearing is to be replaced witha NEW part. Reuse of the center differential case tapered roller bearing should prevent therequirement to re-adjust driven pinion preload.

E. With the SST and the transfer RH bearing sub-assembly in close contact, install the transferRH bearing retainer sub-assembly together with the SST into the transfer case.

NOTICE

• Avoid interference between the case and the retainer and between the SST andthe transfer ring gear mounting case.

• Carefully check the retainer’s O-ring for damage and incorrect fitting.

HINT

• If the engagement is tight, tap theSST with a hammer placing a brassbar on the center of the SST.

• If the SST and retainer are NOT inclose contact, the seal for the innerend of the retainer may NOT beproperly aligned when the retainergoes into position. This may resultin the lip of the oil seal being rolledback during installation.

• If the SST and retainer are NOTin close contact, the center ofthe retainer or transfer ring gearmounting case may come out ofposition when the retainer is beinginstalled. This can cause the lip ofthe oil seal to be rolled back.

B. If the preload is too large, replace the bearing spacer with a NEW one.

C. If the preload is too small, repeatedly adjust the preload by tightening the lock nut 5 – 10degrees at a time until the standard value is obtained.

D. If the preload is insufficient even though the tightening torque of the lock nut exceeds themaximum of the standard value, loosen the lock nut and apply gear oil SAE 90 (GL-5) tothe lock nut and the screw thread and base of the driven pinion. Then repeat the precedingoperation. If the tightening torque is smaller than the standard, replace the bearing spacerwith a NEW one and adjust it.SST P/N 09326-20011, 09556-16030Torque: 378 N*m (3855 kgf*cm, 279 ft*lbf)
